Embodiments of the invention are directed to a system for generating video test pattern signals from definitions contained in a text-based definition file. The definition file allows the user to create generic definitions for test signals that can be interpreted to create test signals in a variety of formats, raster sizes, color spaces, sample structures, frame modes, and bit depths. A parametric generator uses one or more engines to then generate the desired test pattern from the definition file.

System for generating text defined test patterns

A relay fault detection and correction system includes a signal detector structured to measure primary and secondary signals, and generates a fault output signal if the signals appear to be unterminated due to a relay not connecting the signals to the loads. A cycle circuit is structured to cause a relay controller to cycle a potentially under-performing relay between its states a number of times after the signal detector generates the fault output.

Methods and apparatus for correcting defects, such as rounded corners and line end shortening, in patterns formed via lithography are provided. Such defects are compensated for 'post-rasterization' by manipulating the grayscale values of pixel maps.
